The step-thru frame makes it easy to get in the saddle without swinging a leg high over the seat, and to stand flat-footed over the bike at a stop – an essential urban-commute feature for some riders.


  • The lightweight, mid-mounted Brose S MAG motor features a brushless internal rotor and produces 90Nm/66 ft. lb. torque, plenty of power assistance to provide a quick launch from a standing start and to give the rider the ability to conquer challenging hills.
  • The Gates™ carbon-fiber belt drive is smooth, quiet, and maintenance-free; it requires none of the frequent lubrication or adjustment of a traditional chain-drive system.
  • The fully enclosed, maintenance-free Enviolo AUTOMATiQ intelligent automatic transmission is an electronically controlled CVT (Constantly Variable Transmission) rear hub that automatically adjusts the gear ratio to maintain the rider’s optimal, personalized pedaling cadence as terrain or speed changes.
  • The RUSH/CTY STEP-THRU is equipped with an integrated, 529Wh lithium-ion battery that can be quickly removed from the frame without tools. The battery locks into the the frame for enhanced security.
  • Front and rear hydraulic disc brakes utilize four-piston calipers and 203 x 2.3mm heavy-duty brake rotors designed to deliver confident braking performance in most riding conditions. This is essential for faster-moving eBicycles and all-weather commuting.
  • Front and rear fenders protect the rider from wheel spray when riding in wet or dirty conditions. Front and rear cargo racks increase utility and practicality, providing a convenient way to carry small loads.
  • Brake lines and electrical wiring are routed through the frame, promoting longer life and less maintenance through protection from the elements and clean, snag-free styling.
